Description

Technical Field

[0001] This invention relates to the field of dust filtration technology, and more particularly to a dust filtration device for noodle processing based on high-efficiency activated carbon adsorption. Background Technology

[0002] During the noodle processing and production process, a large amount of suspended flour dust is generated during the mixing, conveying, and rolling of flour. This dust not only pollutes the workshop production environment and endangers the respiratory health of operators, but may also cause safety hazards due to excessive dust concentration. In addition, it must meet environmental emission compliance requirements, so the dust must be purified through a high-efficiency filtration device before it can be discharged.

[0003] Currently, activated carbon adsorption technology is widely used for dust filtration in noodle processing workshops. Its core technology utilizes the rich pore structure and large specific surface area of ​​activated carbon to achieve physical adsorption of fine dust. Common forms include granular activated carbon, columnar activated carbon, and activated carbon filter cartridges.

[0004] However, in existing dust filtration devices, the adsorption performance of activated carbon depends on its surface and internal pore structure. Since the pore inlet size has a certain threshold, when dusty gas comes into contact with activated carbon, large dust particles and fibrous impurities, whose particle size is larger than the pore inlet size, cannot enter the pores and can only preferentially adhere to the surface of the activated carbon. The dust adhering to the surface will accumulate rapidly in a short time. These accumulated dust particles squeeze and stick together to form a dense blockage layer that completely covers the pore inlets on the surface of the activated carbon. As a result, a large number of unused effective pores inside the activated carbon cannot come into contact with the gas to be treated, the adsorption area decreases sharply, and the adsorption efficiency drops sharply, affecting the gas purification efficiency. Summary of the Invention

[0005] In order to solve the problems in the background art, the present invention proposes a dust filtration device for noodle processing based on high-efficiency activated carbon adsorption.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A dust filtration device for noodle processing based on high-efficiency activated carbon adsorption includes a frame, an air inlet, an air outlet, and a collection bin, and further includes: Inner cylinder one, which is fixed inside the frame at one end near the air inlet, and is equipped with a filter mechanism for primary filtration of dust. Inner cylinder two, the inner cylinder two is fixed inside the frame near one end of the air outlet, the inner cylinder two has a mesh plate one fixedly connected inside and a mesh plate two slidably provided, a high-efficiency activated carbon block is provided between the mesh plate one and the mesh plate two, and a pushing member is provided on the side of the mesh plate two away from the high-efficiency activated carbon block for pushing the mesh plate two to squeeze the high-efficiency activated carbon block; A cutting groove is provided on the inner top surface of the inner cylinder 2. The cutting groove is equipped with a cleaning mechanism for adsorbing dust on the surface of the high-efficiency activated carbon block, and a grinding component for maintaining the working performance of the cleaning mechanism. The discharge port is located at the bottom of the inner cylinder and is connected to the collection bucket. A sealing element for controlling its opening and closing is provided inside the discharge port.

The slider is slidably disposed in the sliding groove, and a return spring is provided between the slider and the sliding groove.

[0010] Preferably, the drive mechanism includes a multi-section electric rod that is movably hinged within a U-shaped frame, and the movable end of the multi-section electric rod is movably hinged to the tool holder; The top of the blade holder is rotatably provided with a short shaft, and the U-shaped frame is provided with an adjustment component for adjusting the posture of the cutting scraper in coordination with the movement of the short shaft.

[0011] Preferably, the adjusting member includes a straight groove formed on the U-shaped frame, an arc-shaped groove formed at one end of the straight groove, and a vertical groove formed at the end of the arc-shaped groove away from the straight groove.

[0014] Preferably, the mesh diameters of filter screen one, filter screen two, and filter screen three decrease sequentially, forming a multi-level gradient filtration structure.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: This invention uses a multi-section electric rod to drive the blade holder, which in turn moves the short shaft along straight, arc-shaped, and vertical grooves.

It also facilitates the sharpening of the cutting blade, keeping it consistently sharp and ensuring the effectiveness of subsequent cleaning operations. Furthermore, it enables automatic opening and closing of the discharge port and dust collection without manual intervention, significantly improving operational efficiency and reducing maintenance costs.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1 - Figure 10 The present invention provides a technical solution: A dust filtration device for noodle processing based on high-efficiency activated carbon adsorption includes a frame 1, which is integrally molded from stainless steel to ensure structural stability. An air inlet 2 is fixed to one end of the frame 1 and connected to the dust emission pipe of the noodle processing workshop via a flange seal. An air outlet 3 is fixed to the other end of the frame 1 for discharging purified gas. A collection bucket 4 is detachably connected to the bottom of the frame 1 via a snap-fit ​​mechanism to collect the dust generated during filtration. The device also includes: The inner cylinder 5 is welded to one end of the frame 1 near the air inlet 2, and its axis coincides with the center line of the air inlet 2. The inner cylinder 5 is equipped with a filter mechanism for primary dust filtration. The use of the filter mechanism facilitates the preliminary filtration of dust, improves the dust filtration effect, and helps protect the surrounding environment.

[0020] The inner cylinder 2 9 is bolted to the end of the frame 1 near the air outlet 3. It is coaxial with the inner cylinder 1 5 and internally connected. A perforated plate 1 8 is fixed inside the inner cylinder 2 9, and a perforated plate 2 11 is slidably arranged on the side away from the inner cylinder 1 5. Both the perforated plate 1 8 and the perforated plate 2 11 are made of porous stainless steel, ensuring gas flow while limiting the position of the high-efficiency activated carbon block 10. The high-efficiency activated carbon block 10 is placed between the perforated plate 1 8 and the perforated plate 2 11. The high-efficiency activated carbon block 10 has a uniform pore size distribution, a large specific surface area, and hydrophobic and anti-caking properties. Through the use of the high-efficiency activated carbon block 10, fine flour particles can be efficiently physically adsorbed, ensuring purification. The dust emission concentration in the gas meets environmental compliance requirements, preventing ultrafine dust from escaping and causing air pollution, which is beneficial to the protection of the surrounding environment. On the side of the perforated plate 11 away from the high-efficiency activated carbon block 10, there is a pushing component for pushing the perforated plate 11 to compress the high-efficiency activated carbon block 10. Through the use of the pushing component, a pushing force can be continuously applied to the perforated plate 11, so that the high-efficiency activated carbon block 10 is always in a compacted state, ensuring that the gas has sufficient contact with the surface and internal pores of the activated carbon, improving the adsorption efficiency. At the same time, the cut high-efficiency activated carbon block 10 can also contact the perforated plate 8, ensuring that the gas is in contact with the high-efficiency activated carbon block 10, which is beneficial to the filtration of the gas.

[0021] A cutting groove 25 is formed on the inner top surface of the inner cylinder 2 9. The cutting groove 25 is equipped with a cleaning mechanism for adsorbing dust on the surface of the high-efficiency activated carbon block 10, and a grinding component for maintaining the working performance of the cleaning mechanism. The cleaning mechanism facilitates the removal of the clogging layer on the surface of the high-efficiency activated carbon block 10, preventing the air inlet pores of the high-efficiency activated carbon block 10 from being blocked, ensuring that gas can pass through the high-efficiency activated carbon block 10, and improving the working efficiency of gas purification. The grinding component facilitates the grinding of the blade of the cutting scraper 22 in the cleaning mechanism, keeping it sharp at all times, and ensuring the effectiveness of subsequent cleaning operations.

[0022] The discharge port 16 is located at the bottom of the inner cylinder 2 9 and is connected to the collection bucket 4. The discharge port 16 is equipped with a sealing element for controlling its opening and closing. The use of the sealing element makes it easy to seal the discharge port 16, preventing the dust in the collection bucket 4 from returning to the frame 1, which is beneficial to air purification.

[0023] The U-shaped frame 7 is fixed inside the frame 1 above the inner cylinder 2 9. The U-shaped frame 7 is equipped with a drive mechanism for driving the cleaning mechanism. Through the use of the drive mechanism, the surface cleaning of the high-efficiency activated carbon block 10, the grinding of the blade of the cutting scraper 22, and the opening of the discharge port 16 are realized, thereby facilitating the purification of gas.

[0024] In this invention, the cleaning mechanism includes a blade holder 21 slidably disposed in the cutting groove 25. The top of the blade holder 21 extends into the interior of the U-shaped frame 7. A cutting scraper 22 is bolted to the bottom of the blade holder 21. The blade of the cutting scraper 22 is coplanar with the edge of the blade holder 21 on the side away from the air inlet 2. The blade of the cutting scraper 22 is in contact with the surface of the high-efficiency activated carbon block 10 to scrape off the blockage layer on the surface of the high-efficiency activated carbon block 10, thereby preventing the air pores at the air inlet end of the high-efficiency activated carbon block 10 from being blocked, which facilitates the passage of gas through the high-efficiency activated carbon block 10 and is beneficial to the purification of the gas.

[0025] In this invention, the polishing assembly includes a mounting groove on the inner wall of the cutting groove 25 at the end away from the cutting scraper 22. A whetstone 26 adapted to the cutting scraper 22 and used to polish the blade of the cutting scraper 22 is installed in the mounting groove. By using the whetstone 26, it is convenient to polish the blade of the cutting scraper 22, so that the blade of the cutting scraper 22 always remains sharp, and the blade of the cutting scraper 22 is prevented from becoming dull, which would affect the scraping of the high-efficiency activated carbon block 10, and is beneficial to the cleaning of the high-efficiency activated carbon block 10.

[0026] In this invention, the sealing component includes a sealing plate 14 disposed inside the discharge port 16. The size of the sealing plate 14 is adapted to the discharge port 16. By using the sealing plate 14, it is easy to seal the discharge port 16, preventing impurities collected in the collection bucket 4 from returning to the inner cylinder 9, thereby facilitating air purification. A torsion spring shaft 15 is threaded through the sealing plate 14. The torsion spring shaft 15 consists of a shaft and a torsion spring, which keeps the sealing plate 14 in a horizontal state under natural conditions, thereby facilitating the sealing of the discharge port 16. Both ends of the torsion spring shaft 15 are rotatably connected to sliders 17. The inner wall of the frame 1 is provided with a groove 19 that is adapted to the slider 17. The slider 17 is slidably disposed in the groove 19. A return spring 18 is provided between the slider 17 and the groove 19. The return spring 18 is always in a compressed state, so that the sealing plate 14 can be automatically inserted into the discharge port 16 to realize the automatic sealing of the discharge port 16.

[0027] In this invention, the driving mechanism includes a multi-section electric rod 20 that is movably hinged inside the U-shaped frame 7. The fixed end of the multi-section electric rod 20 is hinged to the inner wall of the U-shaped frame 7, and the movable end is movably hinged to the top of the knife holder 21. By using the multi-section electric rod 20, a stable power is provided for the cleaning mechanism, realizing the automated sliding and rotation of the knife holder 21. No manual cleaning is required, which meets the needs of continuous production in noodle processing workshops, improves work efficiency, and reduces labor costs. The top of the blade holder 21 is rotatably equipped with a short shaft 23. The U-shaped frame 7 is provided with an adjustment component to adjust the posture of the cutting scraper 22 in coordination with the movement of the short shaft 23. By using the adjustment component, the cleaning of the high-efficiency activated carbon block 10, the sharpening of the cutting scraper 22 blade, and the opening of the discharge port 16 can be realized, which is beneficial to the purification of gas.

[0028] In this invention, the adjusting component includes a straight groove 24 formed on the U-shaped frame 7, an arc-shaped groove 27 formed at one end of the straight groove 24, and a vertical groove 28 formed at the end of the arc-shaped groove 27 away from the straight groove 24. The straight groove 24, the arc-shaped groove 27, and the vertical groove 28 work together to guide the movement trajectory of the short shaft 23. The short shaft 23 moves within the straight groove 24, enabling the cutting scraper 22 to perform horizontal scraping, thereby cleaning the high-efficiency activated carbon block 10. The arc-shaped groove 27 facilitates the movement of the short shaft 23 from the straight groove 24 to the vertical groove 28. The movement of the short shaft 23 within the vertical groove 28 allows the cutting scraper 22 to move within the whetstone 26, thus achieving the grinding of the cutting scraper 22 and squeezing the sealing plate 14 to open it, thereby opening the discharge port 16 and allowing cleaned impurities to enter the collection bucket 4.

[0029] The short shaft 23 is adapted to the straight groove 24, the arc groove 27 and the arc groove 28 respectively.

[0030] In this invention, the pushing component includes a U-shaped plate 12 fixedly connected inside the frame 1 and close to the air outlet 3. A plurality of compression springs 13 are provided between the U-shaped plate 12 and the mesh plate 11 for continuously applying a pushing force to the mesh plate 11. One end of the compression spring 13 is welded and fixed to the U-shaped plate 12, and the other end abuts against the mesh plate 11. The elastic force of the compression spring 13 continuously applies a pushing force to the mesh plate 11, so that the high-efficiency activated carbon block 10 is always kept in a compacted state, ensuring that the activated carbon block is in full contact with the gas.

[0031] In this invention, the filtration mechanism includes a countersunk groove formed on the inner cylinder 5. A mounting frame 6 is detachably embedded in the countersunk groove. A plurality of slots 32 are evenly formed on the top surface of the mounting frame 6. Each slot 32 is provided with a filter screen 29, a filter screen 30 and a filter screen 31 in sequence along the gas flow direction.

[0032] In this invention, the mesh diameters of filter screen 29, filter screen 30, and filter screen 31 decrease sequentially, forming a multi-level gradient filtration structure to achieve graded interception of dust particles of different sizes, thereby facilitating the filtration of pulverized particles.

[0033] Working principle: When using this invention, the device is first connected to the dust emission pipe of the noodle processing workshop. The gas passes through filter screen 29, filter screen 30 and filter screen 31 in sequence, so that most of the large dust particles are intercepted in advance, avoiding the rapid blockage of the high-efficiency activated carbon block 10 and extending its adsorption cycle. The gas filtered by the filtration mechanism will pass through the mesh of the perforated plate 8 and diffuse evenly to the surface and internal pores of the high-efficiency activated carbon block 10. The high-efficiency activated carbon block 10, with its optimized pore size distribution and large specific surface area, physically adsorbs fine flour particles. At the same time, its hydrophobic modification characteristics effectively prevent dust agglomeration and pore blockage caused by water vapor adsorption, ensuring the long-term adsorption activity. The purified gas passes through the perforated plate 11 and is discharged from the gas outlet 3. The emission indicators meet the environmental protection compliance requirements. As the adsorption time increases, dust gradually accumulates on the surface of the high-efficiency activated carbon block 10, forming a dense clogging layer, which leads to a decrease in adsorption efficiency. At this time, the multi-section electric rod 20 is activated, and the movable end of the multi-section electric rod 20 extends to push the blade holder 21 to slide along the cutting groove 25 away from the whetstone 26. The short shaft 23 at the top of the blade holder 21 first slides horizontally in the straight groove 24, driving the cutting scraper 22 to horizontally scrape along the surface of the high-efficiency activated carbon block 10 to remove the surface clogging dust layer. After the cutting scraper 22 is polished, the blade holder 21 is located between the high-efficiency activated carbon block 10 and the perforated plate 8, which facilitates the reset of the blade holder 21. As the movable end of the multi-section electric rod 20 continues to move, the short shaft 23 moves from the arc groove 27 to the vertical groove 28. When the short shaft 23 slides to the junction of the arc groove 27 and the vertical groove 28, the cutting scraper 22 just enters the whetstone 26. When the short shaft 23 enters the vertical groove 28, as the movable end of the multi-section electric rod 20 continues to extend, it drives the short shaft 23 to move within the vertical groove 28, causing the blade holder 21 to move downward, thereby driving the cutting scraper 22 to move downward. Under the action of the whetstone 26, the cutting edge of the cutting scraper 22 is sharpened, restoring the sharpness of the cutting scraper 22 and ensuring the effectiveness of subsequent cleaning operations. When the cutter holder 21 moves downward, it will squeeze the sealing plate 14, causing the sealing plate 14 to move downward first, and then drive the slider 17 to slide downward along the slide groove 19, thereby opening the discharge port 16. When the slider 17 can no longer move downward, the cutter holder 21 will continue to move downward, causing the sealing plate 14 to rotate around the torsion spring shaft 15, so that the sealing plate 14 is in an inclined state, which makes it easier for dust to fall into the collection bucket 4, thus realizing the collection of dust. After dust collection is complete, the movable end of the multi-section electric rod 20 retracts, causing the short shaft 23 to reset, thereby moving the knife holder 21 upward and relieving the pressure on the sealing plate 14. Then, under the action of the reset spring 18, the slider 17 resets upward, and the torsion spring shaft 15 drives the sealing plate 14 to rotate in the opposite direction under its own torque, finally resealing the discharge port 16. Finally, the short shaft 23 resets along the straight groove 24, allowing the knife holder 21 and the cutting scraper 22 to reset for reuse. After the cutting scraper 22 resets, the high-efficiency activated carbon block 10 contacts the mesh plate 8 under the action of the compression spring 13.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
